Specification of Letters Patent. Patented .A r. 27, 1920.

Application filed ltovember s, 1916. Serial No. 129,682.

To all whom it may concern Be it known that I, FREDERICK C. BARGAR, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Im arovements in Fire-Extin uishers of:

l a a which the following is a specification.

This invention relates to fire extinguishers and is particularly directed to the supporting and casing fstructure' used in connection with containers adaptedto hold the extinguishing chemical and expelling fluid, the container and surrounding casing being so constructed that the user at all times may have a visual indication of the fluid level within the container. Specifically, the fire extinguisher structure includes a glass container and a metallic surrounding shell, which latter is provided with a sight opening, so that the liquid level may be readily ascertained. In combination with these, my invention consists in providing a packing to securely hold the container within the shell, which packing is constructed of strands diagonally arranged with respect to the center line of the extinguisher as a whole, so that none of the strands will completely obscure the liquid level from view.

A further object of this invention consists in combining with the shell and container, a metallic packing made of wire strands interwoven with each other, corrugated and diagonally arranged so that the above objects are further carried out.

The preferred embodiment of my invention is shown in the accompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 shows a fire extinguisher par tially in section to disclose my improved type of packing in combination therewith, and,

Fig. 2 is a horizontal sectionof the structure shown in Fig. 1.

In these views, the extinguisher is shown as comprising an outer shell or casing 1, provided with diametrically opposed sight openings 2. This shell surrounds a glass container 3, which container is adapted to hold the extinguishing chemical and an expelling fluid such as compressed air. This glass container is suitably packed within the shell to guard against longitudinal dis placement by means of any preferred type of packing shown at 4; and 5, as being located adjacent the lower and upper ends respectively. Between these points, I have provided a metallic packing in the nature of a wire] netting 6, whose strands are diagonally arranged with respect to each other.

and'which netting as a whole is corrugated to y'ieldingly center the container within theshell. Inassembling, the container may be wedged in position and held in such position by means of the corrugations of the netting. By means of the diagonal arrangement of the wire strands, none of these strands will entirely obscure the liquid level through the sight openings 2 from view, as might be the case if the strands forming this netting were horizontally and vertically arranged. In this latter case, the horizontal strands might appear at the liquid level and where this liquid and the expeL ling fluid or compressed air are not discernible by color variation, this latter feature would be very objectionable. Further, this wire netting permits the packing to be placed over the sight opening and in this manner gives an additional safe guard against breaking by a blow from the exterior. It may also be pointed out that by arranging the wire strands diagonally and .then corrugating the netting as a whole, all of the wires constituting the netting or packing are bent to conform to the corrugation, which would not be the case if these wires ran vertically and horizontally and then the horizontal wires corrugated only.

What I claim, is:

1. In a fire extinguisher, a substantially transparent containerradapted to hold an extinguishing chemical and an expelling pressure fluid, a shell surrounding said container, said shell being provided with a sight opening to disclose the liquid level, and a toraminated packing located between said shell and container and extending over said sight opening.

2. In a fire extinguisher, a substantially transparent container adapted to hold an extinguishing chemical and an expelling pressure fluid, a shell surrounding said container, said shell being provided with a sight opening to disclose the liquid level and a packing located between said shell and container formed of non-horizontal strands at the point where it underlies said sight opening.

3. In a fire extinguisher, a substantially transparent container adapted to hold an extinguishing chemical and an expelling pressure fluid, a shell surrounding said container, said shell beingprovidedwith a sight opening to disclose the liquid level, and a packing located between said shell and container formed of corrugated wire netting having the strands thereof diagonally arranged with respect to the normal liquid level.

4. In a fire extinguisher, a substantially transparent container adapted to hold an extinguishing chemical and an expelling pressure fluid, a shell surrounding said container, said shell being provided with a sight opening to disclose the liquid level, and a packing located between said shell and container formed of corrugated wire netting having the strands thereof diagonally arranged, said corrugation being arranged to cross said strands in non-parallel.

sight opening to. disclose the liquid level,

and a packing located between said shell and container and extending over said sight 1 opening, said packing being permeable as to sight through said sight opening to disclose the liquid level to an observer.

In testimony whereof I afiix my signature r in presence of two witnesses.

FREDERICK o. BA-neAn.
